If life lacks a teleological point, then aren't you just arguing solipsism? How can you tell whether arguing on Slashdot is any different than barking like a dog?
I'll contend that the universe did come from somewhere, and has a point to it. I'll also contend that, irrespective of the drivel you spout, you behave as if the universe does, too.
So how 'bout we gird our loins and offer me a positive, consistent explanation of where we came from, why we're here, and where we're going. Fine. You reject the Jewish peasant carpenter as an explanation. Got it. It's on you; yours is a long and ignoble line of thought. But offer a superior replacement then, in your 'wisdom', please.
As a perfectly rational fellow, I should be pleased to discard any 'mythology' holding me back from achieving greatness as, say, an Opertating Thetan or something. Lay it out for me, bros.
